Title: Ophthalmic solution of stable povidone-iodine
Inventor: DEIRIIPU BAGUWATSUTO
IPC: A61K47/48
Filed: 1992-03-23
Abstract: PURPOSE: To prepare a new iodophor solution, useful for ophthalmic sterilization without any fear of exudation, etc., even when stored in a glass container and stable according to the U.S. Pharmacopeia standards by adding a prescribed amount of an alkalinizing agent to a solution containing a specific amount of iodine and providing a nonbuffered solution. CONSTITUTION: This stable ophthalmic povidone-iodine solution is prepared by feeding the povidone-iodine in an amount, sufficient to provide the povidone- iodine containing available iodine in an amount effective in sterilizing the solution but incapable of making the solution stable by the effective amount and adding an alkalinizing agent such as sodium hydroxide thereto so as to maintain the available iodine at about 85% to about 120% of the initial amount thereof at about 40 deg.C for 3 months when stored in a glass container at the time of obtaining the ophthalmic sterilizing solution, stable according to the U.S. Pharmacopeia standards when stored in the glass container and comprising the povidone-iodine. The effective amount thereof is nontoxic and nonirritating and the solution is nonbuffered.

Title: Surface-treating solution and process for treating substrate surface
Inventor: TAKAHARA YOICHI
IPC: C11D7/32
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To effectively prevent a substrate from causing the redeposition of metal ions eluted in an alkaline treating soln. by incorporating a specified sequestering agent into the soln. so as to remove the metal staining the surface of the substrate to be treated by using a small amount of the additive. SOLUTION: Since a metal ion coordinated with H2 O or OH in an alkaline treating soln. easily adheres to a substrate, an electron is fed into the metal ion to reduce the positive charge or to make it negative, thereby inhibiting the bonding of the metal ion to the substrate surface. For this purpose, the surface-treating sol. contains at least one of the following sequestering agents (1), (2) and (3):  (1) diethylenetriaminepentaacetic acid of such a concn. that the wt. ratio thereof to the eluted iron ion is at least 3,000:1 and the one to the zinc ion eluted from the treated substrate is at least 30,000:1, (2) triethylenetetraminehexaacetic acid of such a concn. that the wt. ratio thereof to the copper ion eluted from the treated substrate is at least 40,000/1 and the one to the nickel ion is at least 40:1, and (3) glutamic acid of such a concn. that the wt. ratio thereof to aluminum ion eluted from the treated substrate is at least 30,000:1.

Title: Plate cylinder for lithographic plate or intaglio printing plate
Inventor: MATSUMOTO KATSUTOSHI
IPC: B41F31/02
Filed: 1981-04-28
Abstract: PURPOSE:To effectively perform a thick film printing in a plate cylinder for an intaglio printing plate without damping water by accelerating the plate cylinder rotating speed at the inking time and decelerating the speed at the printing time during one revolution. CONSTITUTION:When a plate cylinder 11 and an impression cylinder 13 rotate at the set circumferential speed such as 390mm./sec. and a plate surface 17 approaches an inking roller 31, a microswitch R1 is actuated by the circular-arcshaped surface 45 of a plate cam C1 which rotates at the same angular speed as the cylinder 11. The field resistance of a motor is reduced by this operation to increase tge rotating speed of the motor, and an ink transfer can be preferably performed only to an image part without contamination of non-image part with inking roller group 12 at the set circumferential speed such as, for example, 520mm./sec. When the end of the surface 17 then reaches a position P to be printed, a microswitch L1 is actuated by the cam C1, the cylinder 13 is moved upwardly, the motor is decelerated to a set circumferential speed such as 260 mm./sec., thereby effectively transfer the image onto a material 14 to be printed.

Title: Method for vertically bagging and packaging viscous material
Inventor: MUROI MASAHISA
IPC: B65B9/10
Filed: 1995-02-28
Abstract: PURPOSE: To bag and package a viscous material in the form of a square floor bag. CONSTITUTION: A packaging tube H suspended from a product-charging cylinder 2 is shaped into a square tube by a guide member 25 suspended from the product- charging cylinder 2. Downward of the guide member 25, the packaging tube H is gusseted at each side thereof, thereafter being sealed at two lateral stripes and cut at the center unsealed part between the two lateral stripes over the full width thereof by a laterally sealing and cutting device. The laterally sealing and cutting device is raised to come close to the guide member 25, whereby a square floor is formed by developing the inward gusseted parts on both sides into a triangle planar form. Charging of a viscous material P from a viscous material-charging pipe 24a is started.  When the square floor surface of the packaging tube H is filled with a required amount of viscous material, the laterally sealing and cutting device is lowered at a required speed determined in accordance with the charging amount of the viscous material to pull down the packaging tube H. After the bag is filled with the viscous material P for one bag, the packaging tube H is still pulled down by a required dimension. After that, the laterally sealing and cutting device is opened and raised to be returned to a home position.

Abstract: PURPOSE:To provide a metallic vapor discharge lamp which suppresses the temperature rise of seal sections, prevents the occurrence of cracks, and has a long life. CONSTITUTION:In a metallic vapor discharge lamp sealed with metallic foil conductors 3 in crush seal sections 2 formed at the end sections of a light emitting tube 1 and connected with electrodes 4 to the metallic foil conductors 3, electrode shafts 5 connected to the metallic foil conductors 3 are made of a high-melting point metal with the thermal conductivity lower than that of conventional tungsten, e.g. pure rhenium or rhenium-tungsten alloy, for a lamp used under the tube wall load 20-100W/cm<2>. Since the electrode shafts 5 are made of the high-melting point metal with low thermal conductivity such as pure rhenium or rhenium-tungsten alloy, the ratio that the temperature of electrode tips is transmitted to the crush seal sections 2 via the electrode shafts 5 is made small.

Title: Die for cold forging
Inventor: TSUBOUCHI TAKANORI
IPC: B21J13/02
Filed: 1987-03-19
Abstract: PURPOSE:To prevent the breakdown of the body to be worked by making a press-fitting die into a split die and gradually increasing the die inner diameter approaching to the abutting face toward the abutting face respectively as well. CONSTITUTION:A press-fitting die 1 is divided into an upper split die 2 and lower split die 3 and the die inner diameter D21 of the inner face 21 close to an abutting face 2a of the inner faces of the die 2 is formed so as to gradually increase toward the abutting face 2a as well. Similarly the inner diameter D31 of the inner face 31 close to an abutting face 3a of the inner faces 30 of the die 3 is formed by gradually increasing toward an abutting face 3a. At the time when the body 10 to be worked is cold-forged inside the die 1 the bulging of the body 10 to be worked does not reach to a side wall due to the side area being large near the abutting faces 2a, 3a. The body 10 to be worked is therefore subjected to plastic deformation smoothly at the stage of being extruded even if a step difference exists between the abutting faces. Consequently the breakdown on the surface is prevented.
